Litecoin Core Roadmap 2016

Litecoin Core is the Litecoin reference client. Featuring ‘full node’
capabilities to fully download and validate the Litecoin blockchain as
well as wallet functionality to manage transactions. Litecoin Core is
the most feature rich client out there and contains all the protocol
rules required for the Litecoin network to function. This client is used
by mining pools, merchants and services all over the world for its rock
solid stability, featureset and security.

Litecoin Core v0.13.x will be a major release featuring many protocol
level improvements, code optimizations, the ability to roll out several
soft forks at once and the greatly anticipated segregated witness
innovation. Some of the most notable features include:

Faster signature validation using the libsecp256k library developed by Bitcoin Core developers.

BIP111
- This BIP extends BIP 37, Connection Bloom filtering, by defining a
service bit to allow peers to advertise that they support bloom filters
explicitly. It also bumps the protocol version to allow peers to
identify old nodes which allow bloom filtering of the connection despite
lacking the new service bit.

BIP112
- This BIP is a proposal to redefine the semantics used in determining a
time-locked transaction's eligibility for inclusion in a block. The
median of the last 11 blocks is used instead of the block's timestamp,
ensuring that it increases monotonically with each block.

BIP113
- This BIP describes a new opcode (CHECKSEQUENCEVERIFY) for the
Litecoin scripting system that in combination with BIP 68 allows
execution pathways of a script to be restricted based on the age of the
output being spent.

BIP130
- This BIP adds a new message, "sendheaders", which indicates that a
node prefers to receive new block announcements via a "headers" message
rather than an "inv".

BIP133
- This BIP adds a new message “feefilter”, which serves to instruct
peers not to send “inv”s to the node for transactions with fees below
the specified fee rate.

BIP141 - This BIP defines a new structure called a “witness” that is committed to blocks separated from the transaction merkle tree.

BIP143 - This BIP contains the logic for signature verification for version 0 witness program.

BIP144
- This BIP contains the logic for new messages and serialization
formats for propagation of transactions and blocks committing to
segregated witness structures.
